JAY B RHODES, 0F KALAMAZOO, MICHIGAN, ASSIGNOR TO WESTERN WHEELED i SCRAPER COMPANY, OF AURORA, ILLINOIS, A CORPORATIQN OF ILLINOIS.

DUMP-CAR.

To all whom it mag concern:

Be it known that I, JAY B. RHODES, a. citizen of the. United States, residing at Kalamazoo, in the county of Kalamazoo, State of Michigan; have invented certain new and useful Improvements in Dump-- Cars, of which the following is a specification, reference being had to the accompany ing drawings. o

This invention relates to dumpcars of the type in which the car body orbed is ar ranged to be tilted at either side to discharge its'load, and has particularly to do with du'mp cars in which the dumping and the righting of the car body are effected through the medium of power supplied T It is one of the objects of my invention to provide new and improved ineans for tilting thecar bodyto discharge the load such that by a full stroke of the dumping mechanism the'car body can be tilted into position to dump at either side, as desired, and such that bya full stroke of'the dumping mechanism the car can be again brought to normal horizontal position.

It is another object of my invention to provide dumplng means so arranged that the car body can be tilted to one side and at the same time held against a-sharp sudden dumping movement which m ght have a tendency to ]ill" or shake down a light trestle upon which the car might be located.

It is another object of my invention to provide new and improved means tor looking the car body in horizontal position together with automatically-a'cting means, for releasing the car body when the same is to be dumped.

It is another object of my invention to provide new and improved 'means foroperating the doors or gates which are ordinarily used in connection with cars of this tvpe.

It is. another object of my invention to I improvedevices of this type in sundry. details hereinafter pointed out. V

The means by which I have accomplished these objects are illustrated in the accom-' panying drawings and. are hereinafter specifically described.

In the drawings :Figure l is aside view Patented Jan. 18, 1916.

Referring to the several figures of the drawmgsm which correspondlngparts are indicated by the same reference characters,-

1011 indicate lofigitudinally-extending' I- beams below which are mountedin any suit- .ahle manner suitable trucks axles 12 and wheels 13. as shown diagramcomprising matically in Fig. 1. Mounted upon the I- beams 10'1 1 are standards ll upon which is pivotally mounted the car bed orcar body 15by means of suitable brackets lti, the pivot pins by which such connection is attained being inalinement wherebvthecar body can bev tipped to one side or the other as may be desired. The I-beams 1011-- have mounted upon their ends suitable coupling devices 17 of any approved type. The ,car is provided with end walls 18, which are fixed in position upon the bed, and wit! side gates 1920 which 'are mounted as hereinafter described. The bed 15 is provided with buffers 21 at its corners adapted to engage cooperating bu fl ers mounted in any suitable positlon upon the framework of the car or upon-thetrucks.

Upon; each end 18 of the car there are,

' ,pivotally mounted two arms2324, theitwo 'arms' 23 extending toward oneside of the car having pivotally. mounted upontheir 'outer ends the gate "119, and" the two arms F" :24 extending toward the opposite side of the "car having pivotally mounted upon their 7 .g outer ends the gate 20., As best shown in Fig. '2, the pivot pinsi25 carried bythe gates 19 -*20by which pivotal connection is made relative-to the. central plane of the doors whereby the doors orgates when supported to assume substantially. the position, shown 'in Fig. 2,.stops26 being provided for limit fiside'with a transversely-extending plate 27 adaptedto'beengaged by ahook 28 carried i" which' bracketsare pivotally'mounted upon -"Each of the brackets 31 comprises a plate 33 1 extending across {theiedge otuthe. link 29,

Withgthe brackets 3l= at each side of the car.

shafts revolubly mounted in the framework bi -@saidshaftslhas fixed upon it an arm 36,

dotted {position of the c body the. link I '(is omitted so as to avoid unnecessary ob- {scaring of the drawings. As shown in said, [Fig 2; the pivotal connection between 'the' 35 is turned tothe limit otitsmoti'on in the link has been raised out of contact with such block 39. It is thus'seen that the links- 37 serve normallyto-ho'ld the links -29--31 in their past-center locking position... The I-beam 10 'is provided {with similar blocks 40; one "at each end thereof, adapted to engage the upper end's of the links 37 for holdingthej links 29.31 "at that side of the car likewise in their past-center locking position when the arms 36 arein their lowermost position. As will be readily understood,'when either one of the shafts 3'l-35 is turned in a direction to raise the arms 36 v carriedv thereby, the inner end of .thelink 37 at each end. ot the car is raised out of Contactwiththe block 40 39and swung, upward and inward; forcing the correspond .ing bracket 3l inward about the trunnions 32, forcing the .links 29 at that side of the car upward so as to permit the car body to be tilted toward the opposite side.

As the car body is tilted toward one side or the. other the hooks 28 of the links 29. at the side ofthe car toward Which the car body is tilted are disengaged from the plates 27 while the hooks. 28 of the links 29 at the opposite side of thecar remain in engagement with the plates 27 at that-side of the car. As isbest shown in Fig.1, the hook portions of the links 29 stand-normally in position underneath the arms 23-24 whereby when the car body'is tilted.towardfione side the-arms 23 or 24; at that side of the car are brought into contact with the hookedends of thelinks 29. As isbest shown in Fig. 2,. the upper ended the links' 29 are pivotallyconnected with the arms 23-24 by means of bars 41-42, whereby-the links 29 are held against swinging outward *relative to the arms 23 -24'.' As thejcar body-105 is tilted toward one side the arm 23. or 24 atthat side of the car is held against mov-- ing downward with the car body whereby the gate 19 or 20, at that sideof the car is held in, elevated position whilethe carbody movesaway from the-gate. Y I Coming now to the means for turning the shafts 34-35 as desired for unlocking the car body'for permitting itto be tilted and yforturning the'car body upon its longitudinally-extending pivot pins, 43-44 indicate channel-bar beams extending transversely of the car at about its middle point'and secured in-any suitablemanner to the longitudinallyextending-I-beams 10+11. As shown .in Fig. 1 thebeams 43- 144 are spaced apart, so as. to have secured between them two cylinders 45-46 offanv suitable type pro-- vidod'wit'h a feed'pi'pe 49 by which air under pressure isadapted to be forced into said cylinders for raising the pistonstherein, the air. 'for operating said pistons being supplied from' the locomotive or from any other suitment inwardly-until after the inner end of I J I\ \I able source. The pistons 47-48are provided with piston rods 50-51 which arepivotally' connected at their lower ends with the pistons. Passing through the piston rods 50-51 in-longitudinal direction are two pins 52-53.

54-55 indicatetwo links pivotally mount- 1 ed at their lower ends upon the pin 52 and pivot-ally mounted at their upper ends upon] the longitudinally-extending pivot pin 56by which thebracket 16 at the middle of the car is pivotally connected with the standard 14 carried by the-I-beams 10-11 as above 4 wardly-extending hooks 61.

- .Mounted upon the two sections of each of the shafts 34-35 is a sleeve 62, extending outward from which is an arm .63, each of, said sleeves being held against rotation relative to its shaft. Revolubly mounted upon the shafts 34-35 adjacent to the arms 63 are two rock-arms 64 provided with 1ongitudi-.

nally-extending lugs 65 adaptedto engage the under faces of the arms 63. When one of the pistons47-48 is'forced upward bymeansof. compressed air or in any other suitable manner, the pin 52 or 53 correspond-v .ing with said piston is moved upward,

swinging the arm 55-or 58upward about the pin 56, movlng thelatch lever 59-60 upward and carrying upward'with it the rocklever .64 at that side of the car, serving to move upward the arm 63 contacting therewith, and rotating the shaft 34 or 35 in a direction to raise the arms 36 carried by said shaft for moving inward and upward the links 37 at that side of the car for effecting a release of thelinks 29-31 at that side for permitting thecar body to be tilted toward the opposite side. The end of the rock-lever 64 andthe hook 61 formed on the end of the latch lever 59-60 are so shaped relative to each other that when-the arm 64 has been raised to the desired position for effecting the release of the links 29-31 from locking position, the hook 61 is adapted to automatically slip off from the end of the rocklever 64, whereupon said lever is adapted to drop the normal position in contact with one of the I-beams 10-11.

Mounted upon each of the pins is a yoke comprising a cross-bar 65, as best shown in. Fig. 1, and two arms 66-67.

. 7 right in Fig. 4.

Upon. the lower ends .of' the arm 66-67 below the pins 52-53 are mounted counterbalance we ghts 68 which tend to.hold the beams no mally in the position shown at the The links 55-57 are provided with blocks 69' adapted to be contacted by the arms 66 to limit the movement of the upperends of said arms? outward; 70 indicates lugs carried by the framework adapted to be engaged by the counterbalance weights 68 when the pistons 47-48 are in" their 70 lowermost positions, serving to turnthe upper'ends of the arms66-67 inward as shown at the left in Fig. 4. 71 indicates a 2 bearing pla'te extending across them! at its middle point below the cross-beam' 7 2, said bearing plate'being provided at its outer ends with ribs 73 extending longitudinally of the car. The piston rods 50-51 are pro- Vided at-their upper ends with extensions- I 74-75, respectively, extending above the pins 52-53 at a slight angle relative to said piston rods.

With the car 'body'in position as shown in Fig. 4, with' the operating mechanism at both sides of the car in the condition shown at theleft in said figure, and with'the means for locking the car body against tilting upon its longitudinally-extending pivots in operative past center locking-position, the car is 1n condition to receive its load. Whenever it is desiredto tilt the car toward one side,-

say toward the right in Figs. 4 and 5,- compressed-air orother suitable fluid .under pressure is admitted to the cylinder 45. =The first part of the movement of the piston; 47 9 upward serves to free the counterbalance weight 68 from't-he stop 70, permitting the upper ends of the arm 66-67 to swing out-' I ward under the influence ofthe counterbalance weights. 'At the same time upon the upward movementof-the piston 47 the shaft 34 is turned in clockwise direction through the medium of the latch-lever 59 and the" rock-arm 64, moving the links 29-31 at that side of the car out of their past-centerlocking position. The cross-bar 65 of theyoke mounted upon .the pin 52 very soon'is' brought into contact with the bearing plate 71 near its outer end whereby said crossbar is caused to slide outward along the bearing plate into contact with the rib 73.

-Upon the further movement of the piston .47 the latch-lever 59 is freed from engagement with the rock-arm 64, permitting such rock-arm to fallagain'to normal position,

and the turning movement of the car body through themedium of. the arms--66-67v be gIIIS.

As above described, upon the continuation of the turning movement of the car body the gate 20 is maintained in its elevated position whilethe slide of the car ismoved out of contact with the gate whereby the ma terial in thecar is free-to slide sidewise out -of the'car body. As the carbodvmoves .downward at the right in Fig. 5, the under face ofthe bearing plate 71 comes in con-' tact with-the crossbar 65'of theyokemount- ,20 withouta correspondingturning of the shaft 3 5, whereby the body. locking link 29 at that :SldB'Of the caris maintained inits past-cened uponthe pin 53,1novingthe arms 66 67 I of said yoke inwardagainstthe action of the. counterbalance weights 68- carried by said arms. Aszthe arm 67 of said yoke moves inw'ard a P111176 extending-in a longitu'di- .nal direction from said arm is brought intocontact with the upper end of the latch-lever I 60, releasing-said latch-lever from engagement with the outer end of the rock-lever 64.

When the car is to be 'righted, the compressed air. or other suitable fluid under pressure is admitted to the cylinder 46. i As twillbereadilyunderstood, by reason'of the upward without bringing the arms 66 67 arms 6667 being held inward by the bear mg plate 71, the piston 48 is free to move into action to raise thecarbody. By reason of the latch-lever 60 being held bythe pin 76 out of engagement withthe rock-lever 64, thep ston 48 is enabled to be moved upward ter looking position. Upon the movement of the p ston 48upward, the extension 75 of the piston rod 51 is brought into contact Q with the bearing plate 71 causing the car body torise to normal position. As the car body assumes normal position the book 28 carried by the link29 is again-brought. nto engagement with the transversely-extending plate 27 and the gate 20- is again brought nito position along that side of the Year. As the link29 onthe other side ofthe car assumes the position hown in' dotted lines in Fig; 2 just at the close of the right ingop'eration, the link 29'and the link or bracket 3l are caused to move into their past.-

center lockingv position by reason of the 40.

weightof the links 37 and the arms36.

.In case itis desired to dump the contents of the car when in position upon-a trestle,

or under any other circumstances when it is desired .to t lt thecar without a jar or jerk,

a hook 77 (see Fig. 5) carriedby. the pin 56 7 can be thrown about thecross-bar 65 of the elevating yokeat the side of the car toward which the car body isto be tilted, serving tovvhold the arms 66 67 of said yoke out off The piston 47 18, at thejside of the cartoward which dumping operative position.

is desired canfthen beelevated to its upper most position, bringing the extension 7 4 7 5 into contact with the bearing plate 71.

When, thereafter, the piston 4748 at the opposite side of the car is operatedfor tilting the car body, the. one piston can be; permitted to descend as. the other piston is brought to its uppermost position, thus let ting the car body down gradually andea'sily to its du'mpingposition. In Fig. 5', I have showmat the left the positions of the parts for dumping in this-manner, toward the left. With the piston 4;7 in eifectlve engagement withthe car-body as shown, the piston 48 upon anupward stroke for tilting the carbody toward the left will be prevented fro tipping the body abruptly.

By reason of having a .side gate of thecar mounted upon a single pivot,'theigtti'fi'i? is adapted to turn into position paralleli with the bottom of the car body when in i tilted position so as to affordthe "greatest I possible clearance between the gate .and'the otal connection between the links 29 and the side of the car body; By'reason of the;piv-

arms 23-24, the gate or door-l920- when in:elevated position is free torise still far ther relative. to the car body in case such a' movement-1sv necessaryyin order to permit:

the passage of the contents of the car. By reason of the arms 2324 being mounted at connections 25-by which such links are con nected with the doors or gates 19-'20, the

slig tly away from the car body whereby ample clearance'is provided. I v

' y In case it is desired to vremove th'edoors 19-20 entirely from the car body, this may be accomplished by the withdrawal,gt the the car only as regards dumping in one their inner ends'at a-point above thepivo'tal.

Thus in case a" stump 'or other obstruction prevents thejgatefrom becoming properly seated upon the right. .ing of the bed from tilted'dumpting pcsition,' .the'-bed is locked just'the same 5191i the obstruction were not present.
